Armadillo Horizon 3 Hardshell Tent (Left Only)
Armadillo Horizon 3 Hardshell Tent (Left Only)
The Armadillo Horizon 3 is a hardshell rooftop tent that sleeps 3 adults and folds down into a 14-gauge welded aluminum shell with rounded corners. It opens to the left side on a gas-strut hinge, so you lift the lid, the struts do the work, and the tent stands up tall instead of leaving you stooped over. Open dimensions run 75.25" wide by 89" long with 50.5" of headroom — enough room to sit up, change clothes, and spread out three sleeping spots.
Inside is a self-inflating mattress with dual fill ports, mesh-backed windows on every side, a rear vent, and a skylight, so you can move air through the tent and watch the stars at the same time. The ECO13B fabric uses Light Suppression Technology to block heat and morning light, which keeps the tent darker and cooler than a thin nylon tent. It is rated for 4 seasons and comes with a snow pole that tensions the roof into a V to shed rain and snow.
The Horizon 3 carries its own power, too. A built-in module gives you a 12V socket, USB-A, and USB-C wired to an Anderson-style plug, plus a USB LED light bar that runs white, amber, or a blend of both. A duct port with a locking drawstring lets you pipe in a portable A/C unit or diesel heater, and dual T-slot roof rails hold up to 50 lbs of gear on top of the shell. Closed, it measures 55.5" W x 75.25" L x 13.25" H and weighs 246 lbs with the rails and ladder.

How many people does it sleep, and how big is the sleeping area?
It sleeps 3 adults. The sleeping footprint is 68" wide by 83" long by 46" high.
Which way does the "left only" tent open?
It opens to the left side of the shell — the door and ladder deploy off the left. Set up your vehicle so the open side faces your campsite or awning rather than the road.
Is it really a 4-season tent?
Yes. It's 4-season rated, with an insulating welded shell, ECO13B fabric and Light Suppression Technology, mesh-backed windows for airflow, and a snow pole that tensions the roof into a V to shed rain and snow.
Will condensation build up inside?
Some condensation is normal in any sealed tent in cold weather. Cross-ventilate using the side windows, rear vent, and skylight — the mesh keeps bugs out while air moves through. Letting the fabric dry fully before you close it for a while also helps.
Can I run a heater or air conditioner inside?
Yes. There's a duct port (about 4.5–5") with a locking drawstring sized for portable A/C or diesel-heater ducting.
What roof rack or crossbars do I need?
Mount it on heavy-duty crossbars rated for the tent plus its occupants. Crossbars up to 3.25" wide work with the included T-bolt brackets. Always confirm your rack and vehicle's dynamic (driving) and static (parked) load ratings before mounting. Plan on two people for the lift — it weighs 246 lbs.
Does it have onboard power and lighting?
Yes. The power module has a 12V socket, USB-A, and USB-C wired to an Anderson-style plug, plus a USB LED light bar with white, amber, and blended modes.
